Paver Repair & Re-Sanding in Harrison Township

Interlocking pavers carry weight as a team. The sand in each joint passes a load from one paver to its neighbors, which the Concrete Masonry and Hardscapes Association (CMHA) calls interlock, and the compacted base underneath carries it from there. CMHA's construction guide sizes that base by use: at least 4 inches of compacted base under a patio or walk and at least 6 under a driveway, thicker on cold or wet ground.

That difference matters on the inland streets west of Jefferson Ave, where the 1950s to 1970s subdivision lots often have a second driveway that holds a boat trailer. If that pad was built as patio paving, it carries vehicle loads on a base sized for foot traffic. The wheel paths show it first: pavers dipping where the tires sit, joints opening, sand gone. CMHA notes that tires pull sand from joints and that a saturated bedding layer pumps out under traffic.

Water raises the stakes near the shore. On the canal and river lots, from Lakeside to the marina row along S River Rd, the ground sits low, drains slowly, and stays damp by the seawall. Under vehicular paving on slow-draining soil, CMHA recommends drain pipe beneath the base. Adding drainage is construction rather than repair, so where a sunken pad needs it, the estimate says that instead of pricing a reset over the same wet base.

Winter adds the blade. CMHA advises resetting any paver that stands more than 1/8 inch above its neighbors before snow season, because shovels and plows catch the raised edge, and it suggests shoveling diagonally to the pattern. A failed edge restraint lets the outer row tip outward, and a tipped edge paver is exactly the lip a plow finds.
